Application filed April 29, 1898.

To roll wl'wm it may concern:

30 it known that I, GEORG R; EAGER, of Newton, county of Middlesex, State of Massachusetts, have invented an Improvement in Sharpening Devices for-Pencils, &c., of which the followingdescription, in connection with the accompanying drawings, is a specification like letters on the drawings representing like parts. 1o Thisinvention hasfor its object the production of a very simple, cheap, and strong de vice for sharpening pencils and the like with rapidity an d'effectivel y,whereby an elon gated conical point will be produced Witha minimum of breakage.

Various features of my invention will be hereinafter described in the specification and particularly pointed out in the claims.

' Figure 1, in side elevation and partially broken out, represents a sharpening apparatus embodying myinvention. Fig. 2 is afront View thereof, with the dust or chip collecting hood removed, the bearing for the shaft of p the abraplingor cutting disl; being partly broken oi t. Fig. 3 is a transverse sectional view of the apparatus shown in Fig. 2, on the line a: a; thereof. Fig. 4 is a side elevation of thelcarrier or holder and the abradin g or cutting disk,, with the concave-convex head of the stand in section; and Fig; 5 is a top or plan View of the carrier or holder.

A suitable stand A is provided with preferably a concavo-convex or cup-like head A and a foot/A to be attached to a table or other suitable support, the said head having an elongated bearing 40, extended from the center of its convex back. the head is shouldered, as atct", to receive the edge of a hood II-,'which is made circular to.

40 fit the head, the base II of the hood'being inclosed and depending below the cutting or abrading mechanism to collect the chips and dust as formed. Spring-clips 7% are herein shown secured to the hood to be sprung over the edge of the head A, and thereby detachably retain the hood in place.

I have provided a carrier or holder for the pencil or other object to be sharpened, said carrier being herein shown as comprising a body portion c,'reduced at one end to form a journal If, which is supported in the hearing The perimeter of I Serial 1a. 679,165 (No model.)-

a, the shoulder c abutting against the inner end of said bearing, While a suitable crankarm 0 is attached to the journal at the outer end of the hearing. The carrier extends from the concave side of the head A and at its outer end is provided with a tubular receiver 0 for the pencil or other object P to be sharpened, (see Fig. 4,) and the body 0 of the carrier is cut away to form an inclined longitudinally-extended face 0 extending from the perimeter of the orifice c of the receiver a to the axis of the carrier. Referring to Figs. 4 and 5, a longitudinal recess'c is made inthe face c forming a continuation of andconverginginwardly-from the orifice c. A transverse recess or clearance o is made in the body of the carrier at and intersecting the inner end of the recess 0 The tubular receiver 0 is adapted to enter freely an opening in the outer wall of the hood H when the latter is in position. A disk d, provided on its under side with an abrading or cutting surface, herein shown as a series of radiating cutting-blades d is fast on a shaft (2, rotatably mounted in a bearing 0 forming an integral portion of the carrier (Land oblique to the axis thereof, a pinion d being secured to said shaft at the other end of the bearing. This pinion meshes with an annular gear A (see Figs. '2 and 3,) formed on or secured to the face of the head 'A, so that when the carrier 0 is rotated on its axis the disk cl will be carried around therewith and also rotated positively upon its own axis. The abrading or cutting surface of the disk extends over the inclined face 0 of the carrier and in close proximity thereto, and t* e portion of the pencil extended through the re ceiving-orifice and exposed beyoiu the lecess ciwill be acted upon by the disk, to be abraded or cut thereby.

The pencil is held by the operator from rotation, so that the abrading or cutting tool travels around it, the unexposed portion of the pencil atany time being positively and firmly supported by the carrier.

The dotted lines in Fig. l show the general shape of the recess 0", which made conical to coincide with the sharpened end of the pencil.

It'sometimes happens that the lead of a pcnoil will ln'cak-durin the s'nar eninh and to provide an immediate outlet for the broken piece Iprovide the clearance c", which per Jnits the immediate discharge of such piece or pieces-0f lead Without clogging up the app a u I v.

The construction herein set forth is strong, durable, and simple, the bearing 0 for the shaft of the cutting-tool protecting said shaft 'from the action of dust or dirt, while the shaft sustained by said carrier, the cutter bei-ng arranged to rotate in said recess, and

ineans'for rotating the cutter.

2- in a pencil-sharpening device, a stand provided with a carrier, said carrier having a pencil-receiving orifice, a recess extending entirely across the carrier and intersecting the orifice, and a clearance-space adapted to receive broken-off leads and located beyond said.

recess, a cutter and its supporting-shaft sustained'by said carrier,'the cutter being arranged to rotate in said recess and across said clearance-space, and means for rotating the cutter.

3. In a pencil-sharpening device, a stand having a head provided with a fixed gear, a rotary'carriersupported by the head and having a pencil-receiving orifice, and a recess extending entirely across the carrier and intersecting'said orifice, a cntterand its supporting-shaft sustained by said carrier, the cutter being arranged to rotate in said recess, a gear upon the cutter-shaft meshing with the firstmentioned gear, and means for rotating the cutter.

4. In a pencil-sharpening device, a stand having. a concavo-convex head, a rotary-can, rier'supported by the head, and said carrier having a longitudinal orifice'and having a re? cess extending entirely across the same and intersecting theorifice, acutter and its supporting-shaftsustained by the carrier the cutter being disposed to operate respectively in said recess. andin the concavity of the head, and means for simultaneously rotating the carrier and the cutter.

5. In a pencil-sharpening device, a stand provided with a carrier, said carrier having a pencil-receiving orifice'an'd a recessextending entirely across the carrier"anddnte'rsect ing the orifice, a cutter'and it's 'supportin gshaft sustained by Saidcarti'en-the-cutter be ing arranged to operate insaid reces's means for rotating the cutter, a'hda detachableliood to inclose the carrier and" diskand-havihg means to catch chips and other particles fall- I tof the jonrnal portion, and a shaft=bearing-.
